Notes

* Aurora supports UPNP/DLNA.

UPNP support means a wide range of apps can be used for server and control. A few are mentioned below but they are many others. We suggest simply using the one you prefer.

AudioNet Remote Control Point http://en.audionet.de/apps/rcp/

Linn Open Source Apps: http://oss.linn.co.uk/

dBPoweramp Asset UPNP: http://www.dbpoweramp.com/asset-upnp-dlna.htm

\*\* FAT32 - formatting past the Windows 32GB limit

1) The Aurora reads FAT32 only (not NTFS/ExFat/HPF+)
2) OS X formats FAT32 regardless of size.

3) Windows OS by itself is unable to format a drive above 32GB. Third party utilities are required. "FAT32 Formatter" is a basic portable GUI tool that can format drive larger than 32GB. http://www.ridgecrop.demon.co.uk/index.htm?guiformat.htm

*** Wired is always more preferable to Wireless especially when it comes to reception of higher bandwidth music. If you live in a densely populated area, we recommend the use of a wired network (connect Aurora to router via LAN/Ethernet cable).

AUTOMATIC ROOM TAILORING

Why room correction? Because the room is always the 'final component' in the audio chain. The same system will have a different sonic signature if placed along a room compared to if it was placed across a room. This is mainly due to the sound waves 'reflecting' differently and this impacts what we hear. For maximum musical enjoyment, we need well thought out room correction for any audio system.

This is EVEN more prevalent with a one-box solution such as the Aurora as all similar one-box products sound like a mono source because they are....a mono source.

Therefore, the Aurora has built-in 'Auto Room Tailoring' (ART). Once the unit has been placed in the desired location, all the listener needs to do is to press the 'ART' button on the front panel. Using its rear, left and right ultrasonic sensors, the Aurora will automatically set itself up and, after a few seconds, will be ready to play music that fills the room with the spaciousness akin to using a pair of stereo speakers.

How ART works

1) Using the six ultrasonic sensors, it measures the distance to the walls using ultrasound. The distance affects the low frequency response of the speaker and also our 3D room sound system.
2) It then applies frequency response corrections and adjustment to the 3D system based upon the distances measured.
3) Result - consistent realistic sound and a truly spacious sound field with widely varying placement and no damage wrought by over use of DSP (Digital Sound Processing) as all of this is done in the analogue domain.

SOUNDSPACE

The Aurora proudly uses ASP (Analogue Signal Processing) in its room correction system. This means it is uniquely positioned to play music that is unaltered despite using room correction. Most room correction uses DSP.

iFi does not use DSP of this kind in any of its produc ts. The Aurora incorporates sound-matrix technologies that operate entirely in the analogue domain.

SoundSpace is one such technology – this combines the drive unit array with a proprietary configuration which adjusts the channel outputs from specific drivers at certain frequencies. It is based upon classic, tried and trusted recording methodologies.

SoundSpace is fundamental to the Aurora's immersive, room-filling performance, enabling the soundstage to extend beyond the confines of the cabinet with expansive width, height and depth. This gives music a tangible sense of scale and space from two, correctly positioned speakers you simply wouldn't expect from an all-in-one music system.

TRUE BASS

TrueBass is another proprietary sound-tuning technology that operates strictly in the analogue domain. The depth and quality of bass supplied by all-in-one lifestyle systems often leaves a lot to be desired. The TrueBass system, incorporating the two downward-firing bass radiators, ensures that the Aurora delivers genuine bass with realistic depth and definition. Dual-level depth control means you can adjust the bass response according to taste – down to a deeply impressive 27Hz – so that everything from timpani, to a bass guitar, to an electronic bassline is conveyed with power and poise.

With Aurora, you listen in YOUR way.

The passive radiators work like Helmholz resonators. In order to operate correctly in audible range they cover 25Hz - 60Hz only, they must be tuned to a very low frequency - approx. 18Hz - as the resonance causes a cut in output at the self-resonance frequency. Passive radiators often feature extra weights to tune them.

For our custom passive radiators, we selected a suitably heave material to achieve the correct resonance frequency. As an extra benefit, the carbon/ferrite alloy diaphragm, together with the foam layer, is very well dampened. It does not allow the sound from the back of the wideband drivers to escape through the passive radiator and colour the sound.

The carbon/ferrite alloy delivers the required acoustic parameters in a thinner device than other materials would. It is simply the 'appropriate tech' for our requirements.

PURE emotion

At the heart of the Aurora, lies iFi's proprietary amp technology 'PureEmotion' - a hybrid circuit design comprising several key stages. The first of these - the preamp stage - incorporates a Russian 6N3P valve (visible through a window next to the OLED display). This takes the analogue audio signal delivered by the Aurora's DAC (Digital-to-Analogue Converter)

circuitry – based around a chip from ESS Technology's renowned 32-bit Sabre DAC family – and adds gain in preparation for further amplification, imbuing the sound with pure tonality, open imaging and natural fluidity. The resulting low-level signal then passes to the 'current multiplier circuit' power amp stage. This is a super high-speed power amplifier, one that is bespoke and developed in-house.

The iFi current multiplier circuit is entirely different because the switching frequency is fixed at an ultra-high level - around 1.5MHz, hence it has ultra-high resolution. This results in a high level of efficiency, multiplying the current supplied by the valve several thousand-fold, whilst maintaining far greater linearity and lower noise than typical switching amplifiers. Coupled to this is a low-pass circuit and a feedback loop, the latter ensuring the output frequency is ideal for the load, and everything is 'clock-locked' via iFi's GMT (Global Master Timing) circuit to ensure unerring precision. Even the audio-grade super-fast power supply is all globally locked in step.

This ingenious fusion of amp technologies enables a sound that combines purity of tone with a high level of engagement, speed and dynamic gusto, ensuring the emotive quality of music is delivered in full effect.
